Newest 5BA+1DD Hybrid Earphones

After several successful series of hybrid driver earphones, here comes the terminator, KZ ZSX. It features high quality driver configurations which includes two DWEK BA drivers for medium and high frequency, one DD for low frequency and one 30095 driver for high frequency. With this setting, the sound is powerful and comprehensive, dynamic and bright in all respects. While maintaining the previous performance, the high frequency of this model is extended.

Exquisite Craft.

The faceplate is made of zinc alloy while the cavity is made from imported resin. The two different material not only presents an elegant look and shimmer but also be practical and durable. The detachable gold-plated 2 pin cable offers fully upgradability and the limit slot protection design greatly avoids the pin from breaking and prolongs the service life of the interface.

Sounds great but too large for my ears.

The sound of the KZ zSX is fantastic, And I could really tell the impact that the drivers have on the quality of the sound. However the entire apparatus was too large for my ears. I tried different ear foam attachments and it kept putting up against the side of my ear inside. I just couldn’t figure out how to make them work. I’m female and my mother said even when I was a little girl my ears were small. So unfortunately I had to switch back to my other brand which was not a KZ because they fit my ears.

Value for money. Excellent midrange and bass

I was a little hesitant when looking at the IEM market. I have 3 wireless headphones, but the IEM experience is unique. This is exactly what KZ-ZSX offers you. Frequency accuracy and good sound quality.
The price is very satisfactory for the quality they offer you. I highly recommend them! I would give them a 4.5 without any other thought.

Great hardware at a great price

Great Sound. No dropping from ear. Beautiful and resistant. Great for phone calls Love it!

I will try and keep this short. For what I paid for it, they sound amazing. Yes, I upgraded the cable, that made a difference. Ordered tips, hope to get a little more bass. I adjusted the supplied small tips and that did the trick. Ok, no deep bass, but what you get is the full range of bass and depending on your source of music, it is ok, but quality of the bass is great. The mids are the most forward range, Superb, but guitars at the start of rock music will sound a bit louder than than when the rest of the music kicks in. Treble is pleasant for the most part. On a few tracks the treble was barely harsh sounding, so yes, the least quality sounding range of the three (due to the least frequency range of the three) but great for $40 bucks. Final Verdict: Once you get the accessories that will push the price (for me) to $70, it still is a bargain if you like the signature armature sound of the many earbuds that have them. 4.4 stars. Recommended.

Love the KZ ZSX

I have two nice over-the-ear headphones and now I just leave them in the drawer and only use the ZSX IEMs. Their precision and clarity is so much better than the headphones. Noise isolation is reasonable - I can still hear my wife when she call me (that's good) but much other noise is blocked out.
Customer service was good for me. I had a problem with one earpiece and Linsoul promptly sent a replacement.

Nice!! good sound, the cable is a little short, the plug is really ugly, R and L mark in cable is invisible. Eartips must be more technical, accord to the auric.

KZX can't handle.....

Loyal by Odesza

Broke way to fast and the company doesn't care!

I bought these to use only sitting at my desk with a dac and the right side cracked and the ear tip fell off completely making them not usable anymore. I contacted Linsoul and they only offered me a 50% refund and said literally to "just buy another pair" instead of just giving me a replacement pair. Absolute joke of a company. I will not buy your products again if you can't even support your customers.

The best IEM from KZ so far (Full review on Linsoul's Amazon page for the KZ ZSX)

Throughout my two weeks of testing, I did an A/B testing with the ZS10 Pro and the MH750 (modded, 16 core copper cable). I used the included ear tips and the included cable.

SIZE/FIT (5/5)
In terms of size, I find these to be a bit bigger than the zs10 Pro. The ZSX has the best fit out of all of my earbuds.

Cable is a bit odd.

SOUND (5/5)
I've never been so blown away with a set of earbuds upon first impressions. I wouldn't say these are extremely bassy earbuds, compared to the MH755. I feel like the bass on the ZSX are more pronounced. Vocal and instrument separation was very notable with this earbud. They do a very good job of producing small details that I've only been able to experience on the Tin P1.
Compared to the ZS10 Pro, there is more clarity on the ZSX. The ZSX produce better results in the upper end. Both have a similar quality in the bass.
Compared to the MH750, the ZSX has better separation, but there's more bass in the MH750 in terms of quantity. Bass is more pronounced on the ZSX. Upper end is also more pronounced and clearer on the ZSX, but there were times when I experienced a little bit of sibilance, something I don't experience with the MH750.

Overall (4.6/5)
These earbuds are NICE for the price. Cable's a little wacky when it comes to how much these can get tangled up in a day, but the earbuds themselves are SOLID. If you are looking for a pair of earbuds to sit back and chill with, these would be my recommendations.
